being adapted for engagement with said pinion gear, when aforesaid container is rotated to extend in a vertical plane, and a drive shaft on which said pinion gear is mounted to impart rotary motion to the aforesaid container.

HARRY WILLIAMS.

I am aware, that prior to my invention 1' various machines for cleaning cutleryhave been 1n use, but do not beheveattempts have been made to individually retain articles of cutlery to be cleaned, 'nor' has provision been made for ease in loading and unloading, wherebythe hands of the operator will 'be protected in this operation. It will readily be seen that I have invented a device enabling a great number of cutlery articles to be-cleaned and polished at one time with dispatch and efiiciency, also presenting ease of loading and unloading of the articles, and the filling and emptying of the cleaning compound into and out of the device. 7 What I claim is:

1. Ina cutlery cleaning device, the combination vof a frame, a trunnioned shaft mounted therein, provided with an extension shaft, a cylindrical container rotatably mounted upon said extension shaft, said container-being providedwith an annular ring having radially disposed cutlery receiving slots, said ring being so positioned as to provide an annular fluid passage between the ring and container wall adapted to receive the extremities of cutlery when positioned in aforesaid radially disposed slots, the

aforesaid fluid passage being adapted to receive apredetermined amount of cleaning fluid in combination with shot, when said container is in its loading position with aforesaid extension shaft in a vertical plane, cover means on said container, and rest means provided on aforesaid frame to retain aforesaid container in loading position.

2. In a cutlery cleaning device, the com-f bination of a frame, a trunnioned shaft mounted therein,,provided with an extension shaft, a cylindrical container rotatably mounted upon said extension shaft, said container being provided with an annular ring having radially disposed cutlery receiving slots, said ring being so positioned as to provide an annular fiuid'passage between the ring and container wall, adapted to receive the extremities of cutlery when positioned in aforesaid radially disposed slots, the aforesaid fluid passage being adapted to receive a predetermined amount of cleaning fluid in combination with shot, sealing cover means on said container, said container having a gear cast integral with the outer pe riphery thereof, a pinion gear, said first gear
